Comodo Firewall will be upgrading next week to version 3, offering HIPS and sandbox. As a newbee to Firewall fiddling and knowing nothing about HIPS and sandbox, with the exception of what I found on Webopedia, I need a class on these two things in an easily understood way. Does anyone know where I can find info or can anyone explain HIPS and sand box as it pertains to being included in a firewall? Does it just sit there or is it interactive? Thanks in advance.
